Application filed March 17, 1922. Serial No. 544,399;

To all whom it may concern: a

Be it known that I, RAYMOND B. GIL- CHRIST, a citizen of the UnitedStates, and a resident of Newark,in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in DrinkMixers, of which the following is a full, clear, and exact description.

The invention relates to drink mixers.

In machines for this purpose, the liquid constituents of the drink to bemixed are usually poured into a receptacle which is generally designateda shaker, from many different containers disposed away from the mixer.The receptacle with these constituents therein is brought to the mixerand placed in operative relation thereto and is removed from the machineafter each mixing operation to discharge its contents. This is renderednecessary, because so many different ingredients and flavors are used inmaking drinks that they are, in nearly all cases, mixed individually. Itis usually necessary to run the agitator for a considerable period toproperly blend or mix the constituents and, therefore, it is desirablethat provision be made for retaining the receptacle and agitator inoperative relation to permit the dispenser to perform other dutiesduring the mixing operation. In drink mixing, it thus becomes necessaryto frequently place the receptacle, containing the constituents, intocooperative relation to the a itator and to withdraw it from the ma- 0ine to discharge its contents and cleanse the receptacle between mixingoperations.

A desideratumin this art is to expediteand simplify the operationsnecessary to bring the receptacle and agitator into cooperativerelation, to maintain them in such relation, in starting and stopping ofthe motor and the removal of the receptacle. Heretofore, in machineswhereof I am aware (excepting those exhibited in concurrently pendingapplications), it has been necessary in their use to manually manipulatethe receptacle into operative position and withdraw it therefrom and toadditionally perform some separate step or operation, such as loweringthe motor and agitator together. or shifting the agitator and its shaftinto the receptacle and relatively to the motor, or raising and lookinga receptacle support to establishand maintain cooperative relation ofthe receptacle and agitater orto control the operation of the machlne.Another desideratum in this art is to simplify the machine bydispensingwith movable connections in and for the mechrotation of the liquid withthe agitator. It

has also been found desirable to make provision for the withdrawal ofthe agitator from the liquid before the receptacle passes below theagitator, so that it will cleanse itself by centrifugal force anddischarge the adhering material into the receptacle. By producing avortex whilethe receptacle is being withdrawn, the exit of the agitatorfrom the mixed liquid is facilitated, so that the cleansing operationwill occur before the receptacle is completely withdrawn.

One object of the present invention is to provide an improved drinkmixer in which these additional operations or steps are dispensed withand in which provision is made for shifting the agitator to cause it tooperate' eccentrically while the receptacle is locked inoperativeposition and thus accelerate the agitation of the liquid and to cause itto operate concentrically in the receptacle while the receptacle isbeing withdrawn from and shifted into operative position.

Another object of the invention is to provide a receptacle controlledmachine which is equipped so that the receptacle will be manuallymanipulated into and out of its operative position and in which themotor is shifted to shift the agitator relatively to the receptacle, asa result of said manual shift.

Other objects of the invention will more fully appear from the followingdescription.

The invention consists in the several novel features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a vertical section of a machine embodying theinvention, parts being shown in elevation, the receptacle carrier beingin its lowered position.

Cir

Fig. 2 is a horizontai section on line 22 of Fig. 1. Fig. 3 is avertical section, the receptacle carrier being shown in position to holdthe receptacle in operative position. Fig. 4 is a perspective of thereceptacle carrier.

T he invention is exemplified in a machine comprising a base 10, usuailyadapted to rest on a counter or table, a supporting standard 9 securedto said base by bolts 8 and an electric motor 7 which is pivotallysustained and connected by screws 13 in arms 9 formed on the upper endof standard 9. An agitator shaft 1, projected downwardiy from andsecured to the rotor of the motor 7, is provided at its lower end withan agitator 12 of suitable construction, as well understood in the art.Shaft 11 has fixed relation to the rotor of the motor 8., thus avoidinga sliding connection for per initting the agitator to he raised andlowered into the receptacle 19 which contains the material to beIDiXGCl.

An upper arm 23 and a lowerarm 24 rigid with the carrier-standardfil extend rearwardly through aslot 26 in front of standard 5 and are notched, as at 27, to fit aroundthe sides of said slot and slidably guide the upper and lower portionsor the carrier. Lugs 30, projecting laterally from the upper arm 23 andrigid thereon, are adapted to engage-notches 31 in the rear races of theWalls forming the sides of the slot 26 to loci; the carrier and thereceptacie in operative relation to the agitator.

A lever 'has its upper end rigidly secured to the casing of the motor 7and is provided with an elongated verticaliy extending slot as in whichoperates a stud or roller 3? which is carried at the rear end of theupper carrier arm 23. This connection between carrier and the motor isadapted oclr the motor to shift the agitator into r nt positions Whilethe receprnenuai transit toand from its position.

naoaesa the bottom of the receptacle on or over support 2-2 it beingunderstood that the heel; is formed with sufiicient clearance to permitthe angular insertion of the receptacle into the hook. This will causethe receptacle to be locked to the carrier so that the latter will beoperable upwardly and downwardly by the receptacle.' The operator willmanually raise the receptacle until it reaches its operative positionaround the agitator 12. In transit to said position, stud 37, actingupon cam-portion 44 of slot 43, will shift the switch-lever 40relatively to the arm 35 and cause it to pull the switch-button i8downwardly to close the switch and start the motor 7. As the receptaclereaches its operative position around the agitator, lugs 30 will rea hnotches 31. Off-center weight of motor 7, acting through lever-arm 35,will press stud 37 forwardly. causing in 30' to pass into notches 31 andthus lock the carrier and receptacle in their operative position. Inefiecting forward movement of the upper end of the carrier to lock it,stud 37 i will swing lever-arm 35 and the motor about its fulcrum 13 andcause the agitator to be positioned eccentrically in the receptacle.

In such position, the agitator will operate effectively in the contentsof the receptacle. When the mixing operation has been completed, theoperator will grasp the receptacleand push its upper end rearwardlyagainst the oil-center weight. of the motor and leverarm 35 to withdrawlugs 30 from notches 31 and release the carrier and receptacle so theycan be lowered. This backward movement of the upper portion of thecarrier will cause stud 37 to swing motor 7, so that the agitator 12will be'disposed in substantially concentric position in the receptacleduring its withdrawal. By shifting the agitator to this concentricposition. a vortex will be produced while it is still rotating. As aresult. the withdrawal of the agitator from the liquid will be expeditedand it will centrifugally cleanse itself while the receptacle is stillin position to catch the material thrown off by the agitator. During themanual lowering of the receptacle, stud 37 will shift the lower end ofswitch-lever 40 forwardly about its pivot 41 on lever-arm 45 and causeits upper end 42 to push the switch-button 16 upwardly and open theswitch to stop the motor.

The invention exemplifies a drink mixer in which the motor carrying theagitator is shiftable by the receptacle; in which a re-.

celptacle is locked in and operates a carrier w 1Cl] shifts the motorand agitator; in which the agitator shifted transversely to operateeccentrically in the receptacle dur-' ing the mixing operation and morenearly concentrically during placement or removal of the receptacle intoits operative position; in which the motor is suspended in ofiZcenterdriven by and secured to rotate direct relation to automatically retainthe locking means "for the receptacle-carrier in operative relation; andwhich is simple in construction.

The invention is not to be understood as restricted to the details setforth, since these may be modified within the scope of the appendedclaims, without departing from the spirit and scope of the invention. I
